Stereotactic Radiosurgery (SRS) is a non-invasive radiation treatment that can be performed in one single day or spread out over multiple days. Multiple radiation beams are aimed precisely at the tumor to ensure surrounding healthy tissue is unaffected.
There are three types of Stereotactic Radiosurgery mechanisms: Linear accelerator (LINAC), Gamma Knife, or Proton Beam Therapy. LINAC uses xrays (photons) to deliver radiation, Gamma Knife uses gamma rays (electromagnetic radiation), and Proton Beam Therapy uses charged particles to deliver radiation. Your surgeon will discuss which type of radiation is right for you.
Types of tumors that can be treated with stereotactic radiosurgery are acoustic neuromas, pituitary adenomas, arteriovenous malformations, and other types of cancer.
